Title
(EN) SYSTEM AND METHOD FOR IDENTIFYING SUBOPTIMAL MICROPHONE PERFORMANCE
(FR) SYSTÈME ET PROCÉDÉ DESTINÉS À IDENTIFIER UNE PERFORMANCE DE MICROPHONE SOUS-OPTIMALE
Abstract
(EN)
Embodiments disclosed herein may include determining a signal parameter of a first microphone and a second microphone associated with a computing device. Embodiments may include generating a reference parameter based upon at least one of the parameter of the first microphone and the parameter of the second microphone. Embodiments may include adjusting a tolerance of at least one of the first microphone and the second microphone, based upon the reference parameter. Embodiments may include receiving, at the first microphone, a first speech signal, the first speech signal having a first speech signal magnitude and receiving, at the second microphone, a second speech signal, the second speech signal having a second speech signal magnitude. Embodiments may include comparing at least one of the first speech signal magnitude and the second speech signal magnitude with a third speech signal magnitude and detecting an obstructed microphone based upon the comparison.

Des modes de réalisation de la présente invention peuvent comprendre la détermination d'un paramètre de signal d'un premier microphone et d'un second microphone associés à un dispositif informatique. Des modes de réalisation de la présente invention peuvent comprendre la génération d'un paramètre de référence sur la base d'au moins l'un du paramètre du premier microphone et du paramètre du second microphone. Des modes de réalisation de la présente invention peuvent comprendre le réglage d'une tolérance d'au moins l'un du premier microphone et du second microphone, sur la base du paramètre de référence. Des modes de réalisation de la présente invention peuvent comprendre la réception, au niveau du premier microphone, d'un premier signal vocal, le premier signal vocal ayant une première amplitude de signal vocal et la réception, au niveau du second microphone, d'un second signal vocal, le second signal vocal ayant une deuxième amplitude de signal vocal. Des modes de réalisation de la présente invention peuvent comprendre la comparaison d'au moins l'une de la première amplitude de signal vocal et de la deuxième amplitude de signal vocal à une troisième amplitude de signal vocal et la détection d'un microphone obstrué sur la base de la comparaison.
